Lawrence Wright, staff writer for The New Yorker magazine mentioned in his “Double Mystery” article published on August 7, 1995 explained that one out of eighty or ninety live human births produces twins. With the advent of ultrasonography it has been determined that at least one-eight of all natural pregnancies begin as twins. This is evident when the first ultrasound detects twins and the second one does not. So what happens to these twins?
Vanishing Twin Syndrome (VTS) is the term that describes the spontaneous loss and absorption of one fetus in a set of twins or multiples in the uterus. Spontaneous absorption of a twin most often occurs in the first trimester. The remaining fetus continues to grow normally, and the non-developing fetal tissue is slowly reabsorbed by the other twin, the mother or the placenta. This pregnancy complications is now documented because of increased use of 4D ultrasonography in multiple gestations.
What causes Vanishing Twin Syndrome?
- Chromosomal abnormalities which are out of mother’s control
- Improper cord implantation
- Interruption to the embryo’s developing genetic structure
- Fertility treatment
How frequently does vanishing twin syndrome occur?
Women over the age of 30 are more likely to experience Vanishing Twin Syndrome. A conservative estimate is that it happens in around 21-30% of multiple pregnancies.
Symptoms of Vanishing Twin Syndrome
No symptoms other than vaginal bleeding. the bleeding is usually not accompanied by any vamping or other symptoms, but it can be quite heavy and alarming for the mother. Some mothers experience symptoms similar to miscarriage, including mild cramping, bleeding, and pelvic pain. They typically last a few days.
Diagnosis of Vanishing Twin Syndrome
A diagnosis of vanishing twin syndrome is confirmed by an ultrasound examination that shows a yolk sac with specific embryonic parts that is not developing as it should, or by the lack of a heartbeat in one of the fetuses. A problem with one fetus may also be revealed by blood test results that show decreased hormone levels.
Treatment of Vanishing Twin Syndrome
No treatment is required for vanishing twin syndrome that is detected early in the pregnancy. You can continue taking care of yourself the way you did before learning of the vanishing twin, and do not need to do anything differently. Your doctor may want to monitor the health and growth of your remaining twin more carefully and watch you closely for signs of complications. The remaining twin is generally not affected by the vanishing fetus. If a vanishing twin is detected early in your first trimester, there is a very good chance that you will have a normal pregnancy and deliver a healthy single baby.
Why monitoring is required?
Horrible birth defects are more common causing about 20% of the deaths in the first month of life. Others lead to a painful life of disability and medical procedures. Parents can decide to terminate the pregnancy but sometimes abortion law of country to save the life of the mother and child put doctor in difficult position.
Signs that provide evidence of a twin pregnancy
Althea Hayton, founder of Womb Twin and author of ” Womb twin survivors: the lost twin in the Dream of the Womb.” talks about the signs of twin pregnancy that resulted singleton survivor or survivors.
What happens to womb twin survivors?
Althea Hayton has mentioned that womb twin survivors tend create three styles of relationship:
1. Co dependency
2. Self absorption
3. Group responsibility
Psychological characteristics of womb twin survivors
These are people who started life in the womb as a twin but their twin died before or around birth. Research carried out as part of the Womb Twin Survivors Research Project revealed that there are ways to identify womb twin survivors by means of studying their psychological profile.
